Botox is used in dentistry to help repair facial aesthetics (wrinkles or drooping), alleviate pain from TMJ (temporomandibular joint problems), and prevent the possibility of fracturing or damaging dental work. Botox is a muscle relaxant peptide. It is derived from the bacterium Clostridium botulinum, which can be found in a variety of natural sources. Botox’s effects last for a few months, so regular treatments are required to maintain the look and feel.
